Kylian Mbappe suffered a major shock ahead of the FIFA World Cup 2018 when he had to leave France’s training after sustaining an injury on Tuesday. The 19-year old striker, who plays for Paris Saint-Germain, hurt his left ankle due to a tackle from defender Adil Rami and was unable to continue with the practice.

There were reports saying Mbappe will have to go back to France to get his injury checked, but the youngster downplayed the concerns.

“Ice packs? No, it is just a knock,” Mbappe said according to ESPN. “I hit the ball poorly and I fell -- it is nothing serious. It will be treated, and it will go away.”

Mbappe, who had a good season with the Ligue 1 champions, earlier suffered a knock during France’s 1-1 draw against United States, but coach Didier Deschamps said that the injury was not a major one.

France will head into the FIFA World Cup 2018 as one of the favourites and the Euro 2016 runners-up will lock horns with Australia, Peru and Denmark in Group C. Mbappe’s teammate – Antoine Griezmann – sounded quite confident of his team’s chances and said that they are confident ahead of the opener.

“I believe in this group and in the important moments we’ll all be there. In attack we know we can do harm to any team. I feel comfy in the system and I’m close to (manager, Didier) Deschamps. It’s a good setup to get us good results,” Griezmann said during a media interaction in Moscow on Tuesday.
